FIELD OF THE INVENTION

The field of the invention relates to the treatment or prophylaxis of subject with cardiovascular disorder.

BACKGROUND OF THE INVENTION

Although 20 years ago, one treatment fits all was the approach taken which led to formidable “blockbuster” drugs. Today with the sequencing of the human genome and advances in molecular profiling technologies, approaches to drug development are taking a more stratified or personalized approach. These advances increasingly allow for classification of individuals into subpopulations that are at risk of a specific disease, respond to a specific treatment, don't respond to a specific treatment or are at high risk of an adverse event when treated. As such genetic tests can be used to inform diagnosis, prognosis and treatment selection. Numerous studies have shown a relationship between genotype and response to pharmaceutical therapies. This approach has been widely embraced over the past years, particularly in oncology where numerous personalized medicine approaches have been successfully developed and have provided major improvement in clinical outcomes.

In cardiovascular disorders the stratification of the population by genotype for a specific therapeutic intervention has been limited. One of the objectives of the present invention is to demonstrate that the population suffering from cardiovascular disorders might behave differently and consequently may respond differently to a specific treatment. Lowing LDL is an important therapeutic strategy in the management of cardiovascular disease. Indeed statin drugs, which lower LDL, such as Crestor, Lipitor, Pravachol, and Zocar are widely used and among the most prescribed drugs. For some time it has also been generally accepted that increasing HDL could also be therapeutic in cardiovascular disease. Several HDL-raising drugs have been developed including: niacin and CETP inhibitors such as torcetrapib, anacetrapib, evacetrapib and dalcetrapib.

Cholesterylester transfer protein (CETP) also called plasma lipid transfer protein is a hydrophobic glycoprotein that is synthesized in several tissues but mainly in the liver. CETP promotes bidirectional transfer of cholesteryl esters and triglyceride between all plasma lipoprotein particles. The first evidence of the effect of CETP activity on plasma lipoproteins was provided by observations in people with genetic deficiencies of CETP. The first CETP mutation was identified in Japan in 1989 as a cause of markedly elevated HDL-C. Ten mutations associated with CETP deficiency have since been identified in Asians and one in Caucasians. It was found in Japan that 57% of subjects with levels of HDL-C >100 mg/dL have mutations of the CETP gene. In addition, 37% of Japanese with levels HDL-C between 75-100 mg/dL have mutations of the CETP gene. Subsequently, studies of animals treated with an anti-CETP antibody showed that CETP inhibition resulted in a substantial increase in the concentration of HDL-C. Consistent with these observations in CETP deficient patients and rabbits treated with an anti-CETP antibody, it has since been found that treatment of humans with CETP inhibitor drugs increases the concentration of HDL cholesterol and apoA-I (the major apolipoprotein in HDLs). Numerous epidemiologic studies have correlated the effects of variations in CETP activity with coronary heart disease risk including studies of human mutations (Hirano, K. I. Yamishita, S. and MatsuzawaY. (2000) Curr. Opin. Lipido. 11(4), 389-396).

Atherosclerosis and its clinical consequences, including coronary heart disease (CHD), stroke and peripheral vascular disease represents an enormous burden on health care systems internationally. Drugs that inhibit CETP (CETP inhibitors) have been under development for some time with the expectation that they will be useful for treating or preventing atherosclerosis. A number of classes of CETP inhibitor drugs have been shown to increase HDL, decrease LDL in humans and to have therapeutic effects for treating atherosclerosis and cardiovascular disease including dalcetrapib, torcetrapib, anacetrapib, evacetrapib, BAY 60-5521 and others (Table 1).

TABLE 1 Overview of Lead CETP Inhibitor Drugs and Clinical Status Structure Compound Clinical phase

Torcetrapib Phase III discontinued in 2006

Anacetrapib Phase III

Dalcetrapib Phase III trial halted May 2012

BAY 60-5521 Phase I

However there is evidence that these drugs may not be safe and effective in all patients. The clinical trial for torcetrapib was terminated in Phase III due to incidence of mortality in patient to whom torcetrapib and atorvastatin were administered concomitantly compared to patients treated with atorvastatin alone. The clinical trial for dalcetrapib was also halted in Phase III in this case due to a lack of efficacy relative to statins alone. Additional CETP inhibitors are still being pursued in clinical trials and earlier stage development. In general treatment strategies using CETP inhibitors that provide better efficacy, reduced off-target effects would be clinically beneficial. There is a need for biomarkers, methods and approaches for predicting response to CETP inhibitors and accessing risk of adverse events associated with administration of CETP inhibitors.

CETP inhibitors are useful for the treatment and/or prophylaxis of atherosclerosis, peripheral vascular disease, dyslipidemia, hyperbetalipoproteinemia, hypoalphalipoproteinemia, hypercholesterolemia, hypertriglyceridemia, familial hypercholesterolemia, cardiovascular disorders, angina, ischemia, cardiac ischemia, stroke, myocardial infarction, reperfusion injury, angioplastic restenosis, hypertension, and vascular complications of diabetes, obesity or endotoxemia.

Clinical trials have shown that patient response to treatment with pharmaceuticals is often heterogeneous. There a pressing need to improve drug development, clinical development and the therapeutic impact of drugs for individuals or sub-populations of patients. Single nucleotide polymorphisms (SNPs) can be used to identify patients most suited to therapy with particular pharmaceutical agents (this is often termed “pharmacogenomics”). Similarly, SNPs can be used to exclude patients from certain treatment due to the patient's increased likelihood of developing toxic side effects or their likelihood of not responding to the treatment. Pharmacogenomics can also be used in pharmaceutical research to assist the drug development and selection process. Linder et al, Clinical Chemistry 43:254 (1997); Marshall, Nature Biotechnology 15: 1249 (1997); International Patent Application WO 97/40462, Spectra Biomedical; and Schafer et al, Nature Biotechnology 16:3 (1998).

The dalcetrapib mortality and morbidity trial (dal-OUTCOMES) was a double-blind, randomized, placebo-controlled, parallel group, multi-centre study in stable CHD patients recently hospitalized for acute coronary syndrome (ACS). The study was conducted to test the hypothesis that CETP inhibition will reduce the risk of recurrent cardiovascular events in patients with recent ACS by raising levels of HDL-C through CETP inhibition. Eligible patients entered a single-blind placebo run-in period of approximately 4 to 6 weeks to allow for patients to stabilize and for completion of planned revascularization procedures. At the end of the run-in period, eligible patients in stable condition were randomized in a 1:1 ratio to 600 mg of dalcetrapib or placebo on top of evidence-based medical care for ACS. Dalcetrapib is an inhibitor of cholesterol-ester transfer protein (CETP). It has been shown to induce dose-related decreases in CETP activity and increases in HDL-C levels in several animal species and in humans. Decreasing CETP activity, through different approaches, has demonstrated anti-atherosclerotic effects in several animal models. The trial was interrupted in May 2012 by the DSMB on grounds of futility. The dal-OUTCOMES study resulted in unexpected observations related to cardiovascular disease progression. Despite a marked increase in HDL-c, patients on treatment did not show a significant reduction in cardiovascular events and the study was terminated.

Following the termination of dal-OUTCOMES study, it was hypothesized that a subgroup of the patients under study were responding differently to dalcetrapib and that dalcetrapib could be having a significant therapeutic effect in a sub-population of patients. A pharmacogenomic study of the dal-OUTCOMES study population was conducted to study the inter-individual variation in dalcetrapib response and to identify genetic markers for predicting therapeutic response to dalcetrapib, or other CETP inhibitors, for patient stratification and for treatment selection.

SUMMARY OF THE INVENTION

The present invention provides genotyping methods, reagents and compositions for selecting individuals who can benefit from treatment with HDL-raising or HDL mimicking agent, in particular with a CETP inhibitor/modulator, in particular wherein the individuals have cardiovascular disorder. The invention also provides methods of treating patients with a cardiovascular disorder comprising genotyping and selection of patients who may benefit from treatment with HDL-raising or HDL mimicking agent, in particular with a CETP inhibitor/modulator. Surprisingly the pharmacogenomic study of the dal-OUTCOMES patient cohort found single nucleotide polymorphisms (SNPs), genetic markers, associated with an individual's response to dalcetrapib and useful for predicting therapeutic response to HDL-raising or HDL mimicking agent (in particular a CETP inhibitor/modulator) and in treating patients with HDL-raising or HDL mimicking agent (in particular CETP inhibitor/modulator).

The invention further provides methods for treating or preventing a cardiovascular disorder, comprising administering to a subject in need thereof an amount of an HDL-raising or HDL mimicking agent that is effective to treat or prevent the cardiovascular disorder, wherein the subject has a polymorphism at rs11647778 in the subject's ADCY9 gene. In some embodiments, the subject has a genotype of CC at rs11647778. In certain embodiments, the HDL-raising or HDL mimicking agent is niacin, fibrates, glitazone, dalcetrapib, anacetrapib, evacetrapib, DEZ-001, ATH-03, DRL-17822 (Dr. Reddy's), DLBS-1449, RVX-208, CSL-112, CER-001 or ApoA1-Milnano.

Genetic markers detected in the genotyping methods of the invention include: 20 SNPs that occur in the Adenylate Cyclase Type 9 (ADCY9) gene on chromosome 16, rs11647778 and optionally rs1967309, rs12595857, rs2239310, rs11647828, rs8049452, rs12935810, rs74702385, rs17136707, rs8061182, rs111590482, rs4786454, rs2283497, rs2531967, rs3730119, rs2531971, rs2238448, rs12599911, rs12920508, or rs13337675, in particular rs11647778 or rs1967309, which are both in strong linkage disequilibrium together (r²=0.79) and strongly associated with response to an HDL-raising or HDL mimicking agent, in particular a CETP inhibitor/modulator.

Other gene markers of the invention include a SNP in the ADCY9 gene that are either in linkage disequilibrium with rs11647778 or rs1967309 or provided an association signal with clinical events with a statistical P<0.05 and may provide useful surrogate biomarkers of rs11647778 or rs1967309. In one embodiment a surrogate biomarker, consisting of a SNP inherited in linkage disequilibrium with rs11647778 or rs1967309, are detected and the genotype of rs11647778 or rs1967309 are inferred.

The present invention relates to methods of genotyping patients and/or treating patients with HDL-raising drug, in particular a CETP inhibitor. In particular embodiments, the methods comprise assessing the genotype of a patient at rs11647778. Three genotypes at rs11647778 are to predictive of an individual's response to an HDL-raising drug, in particular a CETP inhibitor: CC, CG and GG. Of these the CC genotype is associated with an improved therapeutic response in patients treated with an HDL-raising drug, the CG genotype is associated with a partial response and the GG genotype is associated with a lack of response (non-response). For the purpose of the present invention: patients who carry the CC genotype can benefit from treatment with an HDL-raising drug; patients who carry the CG genotype can benefit from treatment with an HDL-raising drug and patients who carry the GG genotype cannot benefit from treatment with an HDL-raising drug. Two genotypes at rs11647778, CC and CG indicate a therapeutic response to a CETP inhibitor, in particular dalcetrapib, in patients with cardiovascular disorder. In particular, CC genotype for rs11647778 is indicative of greater therapeutic response to a CETP inhibitor, in particular dalcetrapib, in patients with cardiovascular disorder.

The present invention relates to nucleic acid molecules containing polymorphisms or gene variants, variant proteins encoded by these nucleic acid molecules, reagents for detecting the polymorphic nucleic acid molecules, and methods of using the nucleic acid molecules and proteins as well as methods of using reagents for their detection (e.g., primers and probes for use in the genotyping methods of the invention).

In one embodiment the invention provides: methods of detecting the gene variants of the invention and detection reagents, such as probes or primers, for use in these methods.

The invention specifically provides, genetic markers associated with therapeutic response to a HDL-raising or HDL mimicking agent, in particular a CETP inhibitor/modulator, and synthetic nucleic acid molecules (including DNA and RNA molecules) containing the gene variants of the invention. The invention further provides variant proteins encoded by nucleic acid molecules containing such gene variants, antibodies to the encoded variant proteins, computer-based and data storage systems containing the novel gene variant or SNP information, methods of detecting these SNPs in a test sample, methods of identifying individuals who respond therapeutically when administered a HDL-raising or HDL mimicking agent, in particular a CETP inhibitor/modulator, based on the presence or absence of one or more of the gene variants of the invention or the detection of one or more encoded variant products (e.g., variant mRNA transcripts or variant proteins), and methods of treating individuals who have a cardiovascular disease who carry one of more of the gene variants of the invention.

Exemplary embodiments of the present invention further provide methods for selecting or formulating a treatment regimen (e.g., methods for determining whether or not to administer HDL-raising or HDL mimicking agent, in particular CETP inhibitor/modulator treatment to an individual).

Various embodiments of the present invention also provide methods for selecting individuals to whom a HDL-raising or HDL mimicking agent (in particular CETP inhibitor/modulator) can be therapeutically administered based on the individual's genotype, and methods for selecting individuals for participation in a clinical trial of a HDL-raising or HDL mimicking agent (in particular a CETP inhibitor/modulator) based on the genotypes of the individuals (e.g., selecting individuals to participate in the trial who are most likely to respond positively and/or excluding individuals from the trial who are unlikely to respond positively to treatment based on their genotype(s), in particular their genotype is CC at rs11647778, TT at rs2238448, and/or AA at rs1967309, or selecting individuals who are unlikely to respond positively for participation in a clinical trial of alternative drug that may benefit them.

The nucleic acid molecules of the invention can be inserted in an expression vector, to produce a variant protein in a host cell. Thus, the present invention also provides for a vector comprising a SNP-containing nucleic acid molecule of the invention, genetically-engineered host cells containing the vector, and methods for expressing a recombinant variant protein using such host cells. In another specific embodiment, the host cells, SNP-containing nucleic acid molecules, and/or variant proteins can be used as targets in a method for screening or identifying therapeutic agents that are HDL-raising or HDL mimicking agent (in particular CETP inhibitor/modulator).

Exemplary SNPs of ADCY9 that can be determined/evaluated in the herein provided method for identification of an improved response to dalcetrapib or for treating or preventing a cardiovascular disease in a patient are those where the mutation results in a change in the nucleotide sequence at position 4,062,592, 4,065, 583, 4,059,439 and 4,051,380, (genome assembly GRCh37.p5) also known as single nucleotide polymorphisms with identifiers rs12595857, rs1967309, rs2238448, and rs11647778, respectively, as shown in SEQ. ID. NO.2 1, 19 and 21.

The present invention is based on the identification of genetic polymorphisms that are predictive of an increased likelihood that treatment with a HDL-raising or HDL mimicking agent, in particular CETP inhibitor/modulator may benefit patients with cardiovascular disorders.

DETAILED DESCRIPTION OF THE INVENTION

Various features and embodiments of the present invention are disclosed herein, however other features of the invention, modifications and equivalents will be apparent to a person skilled in the relevant art, based on the teachings provided. The invention described is not limited to the examples and embodiments provided, various alternatives equivalents will be appreciate by those skilled in the art. As used herein, the singular forms “a”, “an” and “the” include the plural unless the context clearly dictates otherwise. For example, “a” cell will also include “cells”.

The term “about” when used in connection with a referenced numeric indication means the referenced numeric indication plus or minus up to 10% of that referenced numeric indication. For example, “about 100” means from 90 to 110.

An “allele” is defined as any one or more alternative forms of a given gene. In a diploid cell or organism the members of an allelic pair (i.e. the two alleles of a given gene) occupy corresponding positions (loci) on a pair of homologous chromosomes and if these alleles are genetically identical the cell or organism is said to be “homozygous”, but if genetically different the cell or organism is said to be “heterozygous” with respect to the particular gene.

A “gene” is an ordered sequence of nucleotides located in a particular position on a particular chromosome that encodes a specific functional product and may include untranslated and untranscribed sequences in proximity to the coding regions. Such non-coding sequences may contain regulatory sequences needed for transcription and translation of the sequence or introns etc. or may as yet to have any function attributed to them beyond the occurrence of the SNP of interest.

“genotyping” refers to the determination of the genetic information an individual carries at one or more positions in the genome. For example, genotyping may comprise the determination of which allele or alleles an individual carries for a single SNP or the determination of which allele or alleles an individual carries for a plurality of SNPs. For example, at rs1967309 the nucleotides may be a A in some individuals and a G in other individuals. Those individuals who have a A at the position have the A allele and those who have a G have the G allele. In a diploid organism the individual will have two copies of the sequence containing the polymorphic position so the individual may have a A allele and a G allele or alternatively, two copies of the A alleles or two copies of the G allele. Those individuals who have two copies of the G allele are homozygous for the G allele, those individuals who have two copies of the A allele are homozygous for the A allele, and those individuals who have one copy of each allele are heterozygous. The alleles are often referred to as the A allele, often the major allele, and the B allele, often the minor allele. The genotypes may be AA (homozygous A), BB (homozygous B) or AB (heterozygous). Genotyping methods generally provide for identification of the sample as AA, BB or AB.

The term “comprising” is intended to mean that the compositions and methods include the recited elements, but do not exclude others.

“HDL-raising or HDL mimicking agent” refers to compounds which increase HDL levels by either one of the following mechanisms: CETP inhibition/modulation, PPAR agonism, LXR agonism, HM74 agonism (niacin receptor) thyrotropin hormone receptor agonism, Inhibitors of lipases and HDL catabolismApoA1 inducers, compounds which provide at least one of the HDL athero-protective activities such as compounds that would increase cellular lipid efflux (cholesterol and/or phospholipids), have antioxidant and anti-inflammatory activities. In particular HDL mimicking agent is ApoA1 and ApoA1 derivatives (such as apoA1 Milano, ApoA1 Paris) and other analogues, reconstituted HDL containing ApoA1 and or ApoAII and the appropriate lipids such as phospholipids. ApoE, derivatives, analogues, and peptidomimetics of amphipathic lipoproteins.

More particularly examples of CETP inhibitor/modulators are dalcetrapib, anacetrapib, evacetrapib and torcetrapib, preferably dalcetrapib, anacetrapib and evacetrapib. Most particularly the HDL-raising or mimicking agent according to the invention would refer to a CETP inhibitor/modulator, especially when the CETP inhibitor/modulator is dalcetrapib. “CETP inhibitor/modulator” refers to a compound which decreases CETP activity (assessed by standard transfer assays) by inhibiting CETP and/or inducing conformational changes of the CETP polypeptide once bound to the CETP polypeptide. The CETP conformational changes of the CETP polypeptide allow CETP activity to proceed between HDL particles and increase its recycling/turnover bay increasing the production of nascent pre-beta HDL formation. Preferably the CETP inhibitor/modulator refers to all compounds that would bind to cysteine 13 of the CETP polypeptide. More preferably, the “CETP inhibitor/modulator” is selected from S-[2-[1-(2-ethylbutyl)cyclohexylcarbonylamino]-phenyl]2-methylthiopropionate, 1-(2-Ethyl-butyl)-cyclohexanecarboxylic acid (2-mercapto-phenyl)-amide and or bis [2-[1-(2-ethylbutyl)cyclohexylcarbonylamino]phenyl]disulfide. Most preferably, “CETP inhibitor/modulator” is S-[2-[1-(2-ethylbutyl)cyclohexylcarbonylamino]-phenyl]2-methylthiopropionate as a prodrug or 1-(2-Ethyl-butyl)-cyclohexanecarboxylic acid (2-mercapto-phenyl)-amide as its active metabolite.

“Anacetrapib” refers to ((4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-{[4′-fluoro-2′-methoxy-5′-(propan-2-yl)-4-(trifluoromethyl)[1,1′-biphenyl]-2-yl]methyl}-4-methyl-1,3-oxazolidin-2-one) also known as MK 0859, CAS 875446-37-0 or a compound of formula (X_(A)).

BAY 60-5521 as well as methods of making and using the compound are described in WO2006063828.

“Treatment” refers to both therapeutic treatment and prophylactic or preventative measures. Those in need of treatment include those already with the disorder as well as those in which the disorder is to be prevented or delayed.

The term “polymorphism” “polymorphism site” Polymorphic site” or “single nucleotide polymorphism site” (SNP site) or “single nucleotide polymorphism” refers to a location in the sequence of a gene which varies within a population. A polymorphism is the occurrence of two or more forms of a gene or position within a gene “allele”, in a population, in such frequencies that the presence of the rarest of the forms cannot be explained by mutation alone. Preferred polymorphic sites have at least two alleles. The implication is that polymorphic alleles confer some phenotype variability on the host. Polymorphism may occur in both the coding regions and the noncoding region of genes. Polymorphism may occur at a single nucleotides site or may involve an insertion or a deletion. The location of such a polymorphism may be identified by its nucleotide position in the gene, on the chromosome or on the transcriptor by the amino acids that is altered by the nucleotide polymorphism. Individual polymorphisms are also assigned unique identifiers (“Reference SNP”, “refSNP” or “rs#”) known to one of skill in the art and used, e.g., in the Single Nucleotide Polymorphism Database (dbSNP) of Nucleotide Sequence Variation available on the NCBI website.

The terms “linkage disequilibrium” or “in linkage disequilibrium” or “LD” refers to the non-random association of alleles in a collection of individuals, in other words it is the preferential segregation of a particular polymorphic form with another polymorphic form at a different chromosomal location more frequently than expected by chance. By opposition the alleles that co-occur at expected frequencies are said to be in “linkage equilibrium”.

The “rs” prefix refers to a SNP in the database found at the NCB1 SNP database http://www.ncbi.nlm.nih.gov/snp/?term. The “rs” numbers are the NCBI rsSNP ID form.

The term “sample” includes any biological sample taken from a patient or individual including a cell, tissue sample or body fluid. For example, a sample may include a skin sample, a cheek cell sample, saliva or blood cells. A sample can include, without limitation, a single cell, multiple cells, fragments of cells, an aliquot of a body fluid, whole blood, platelets, serum, plasma, red blood cells, white blood cells, endothelial cells, tissue biopsies, synovial fluid and lymphatic fluid. In particular “sample” refers to blood cells.

The term “therapeutic agents” refers to agents capable of treating or preventing cardiovascular disorder. As used herein, an agent “capable of treating or preventing cardiovascular disorder” refers to a molecule that is capable of treating and/or preventing a cardiovascular disorder in humans and/or in a cellular or animal model of said cardiovascular disorder.

An “improved response polymorphism”, “improved response genotype” or “responsive genotype” as used herein refers to an allelic variant or genotype at one or more polymorphic sites within the ADCY9 gene as described herein (for example, rs11647778/CC), which predicts that a subject will respond therapeutically and benefit from treatment with an HDL-raising or HDL mimicking agent (which may be measured by a decreased number of cardiovascular events) as compared to an allelic variant or genotype or polymorphism (for example, rs11647778/CG or rs11647778/GG) which predicts that a subject will respond less to HDL-raising or HDL mimicking agent administration. “Reduced response” “partial response”, “non response” or “lack of therapeutic efficacy”, may be measured by a relative increase in number of cardiovascular events relative to subjects having an “improved response genotype”. Alternately, “improved response”, “responder” or “therapeutic efficacy” may be measured by a relative decrease in number of cardiovascular events relative to subjects that carry polymorphisms associated with “non response” or “partial response” to a HDL-raising or HDL mimicking agent. In particular rs11647778/CC, and optionally rs12595857/GG, rs1967309/AA, rs111590482/AG, rs111590482/GG, rs11647828/GG, rs12935810/GG, rs17136707/GG, rs2239310/GG, rs2283497/AA, rs2531967/AA, rs3730119/AA, rs4786454/AA, rs74702385/GA, rs74702385/AA, rs8049452/GG, rs8061182/AA and rs2238448/TT are improved response genotypes. More particularly, rs11647778/CC and optionally rs1967309/AA, and rs2238448/TT is and improved response genotype. Most particularly, rs111647778/CC and rs1967309/AA is improved response genotype.

“Cardiovascular events” as used herein refers to cardiovascular death, non-fatal myocardial infarction (MI), non-fatal stroke of ischemic origin, hospitalization for unstable angina and coronary revascularization.

“Oligonucleotides” as used herein are variable length nucleic acids or polynucleotides. Such oligonucleotides may be useful as probes, primers and in the manufacture of microarrays (arrays) for the detection and/or amplification of specific nucleic acids. Such DNA or RNA strands may be synthesized by the sequential addition (5′-3′ or 3′-5′) of activated monomers to a growing chain, which may be linked to an insoluble support. Numerous methods are known in the art for synthesizing oligonucleotides for subsequent individual use or as a part of the insoluble support, for example in arrays (BERNFIELD M R. and ROTTMAN F M. J. Biol. Chem. (1967) 242(18):4134-43; SULSTON J. et al. PNAS (1968) 60(2):409-415; GILLAM S. et al. Nucleic Acid Res. (1975) 2(5):613-624; BONORA G M. et al. Nucleic Acid Res. (1990) 18(11):3155-9; LASHKARI D A. et al. PNAS (1995) 92(17):7912-5; MCGALL G. et al. PNAS (1996) 93(24): 13555-60; ALBERT T J. et al. Nucleic Acid Res. (2003) 31(7):e35; GAO X. et al. Biopolymers (2004) 73(5):579-96; and MOORCROFT M J. et al. Nucleic Acid Res. (2005) 33(8):e75). In general, oligonucleotides are synthesized through the stepwise addition of activated and protected monomers under a variety of conditions depending on the method being used. Subsequently, specific protecting groups may be removed to allow for further elongation and subsequently and once synthesis is complete all the protecting groups may be removed and the oligonucleotides removed from their solid supports for purification of the complete chains if so desired.

The term “genotype” refers to the genetic constitution of an organism, usually in respect to one gene or a few genes or a region of a gene relevant to a particular context (i.e. the genetic loci responsible for a particular phenotype). In particular, the specific combination of alleles at a given position in a gene, such as for example, the genotypes AA, AG, or GG which are possible genotypes of the rs1967309 SNP.

A “phenotype” is defined as the observable characters of an organism. Tables 2, 3, 4 and 5 show a genotype correlation for ADCY9 SNP with values representing an indication of responsiveness to treatment of cardiovascular disorders with a HDL-raising or HDL mimicking agent.

The term “biomarker” as used herein refers to a sequence characteristic of a particular variant allele (polymorphic site, such as a SNP) or wild-type allele. Biomarker also refers to a peptide or epitope encoded by a particular variant or wild-type allele.

The term “surrogate marker” as used herein refers to a genetic variant, including a SNP, that is present in linkage disequilibrium with an improved response genotype of the invention, in particular rs11647778/CC.

The term “genetic marker” as used herein refers to variants of polymorphic sites of a particular gene that are associated with response to a HDL-raising or HDL mimicking agent, in particular CETP inhibitor/modulator. In particular ‘genetic marker’ as used herein refers to variants of polymorphic sites in the ADCY9 gene that are associated with response to a HDL-raising or HDL mimicking agent, in particular a CETP inhibitor/modulator.

Three genotypes at rs11647778 are predictive of an individual's response to an HDL-raising drug, in particular a CETP inhibitor: CC, CG and GG. Of these, the CC genotype is associated with an improved therapeutic response in patients to an HDL-raising drug, the CG genotype is associated with a partial response, and the GG genotype is associated with a lack of response (non-response). For the purpose of the present invention: patients who carry the CC genotype can benefit from treatment with an HDL-raising drug; patients who carry the CG genotype can benefit from treatment with an HDL-raising drug, and patients who carry the GG genotype cannot benefit from treatment with an HDL-raising drug. The CC and CG genotypes at rs11647778 in patients with a cardiovascular disorder indicate a therapeutic response to a CETP inhibitor, in particular dalcetrapib. In particular, the CC genotype at rs111647778 in patients with a cardiovascular disorder is indicative of a greater therapeutic response to a CETP inhibitor, in particular dalcetrapib.

Three genotypes at rs2238448 are predictive of an individual's response to an HDL-raising drug, in particular a CETP inhibitor: TT, TC and CC. Of these three genotypes, the TT genotype is associated with an improved therapeutic response in patients treated with an HDL-raising drug, whereas the CC genotype is associated with a lack of response (non-response). Patients who carry the TC genotype can benefit from treatment with an HDL-raising drug as this genotype is associated with a partial response. For the purpose of the present invention: patients who carry the TT or CT genotype can benefit from treatment with an HDL-raising drug and patients who carry the CC genotype cannot benefit from treatment with an HDL-raising drug. The TT genotype at rs2238448 in patients with a cardiovascular disorder indicates a greater therapeutic response to a CETP inhibitor, in particular dalcetrapib, as compared to other genotypes.

In certain methods described herein one or more biomarkers are used to identify or select individuals who will benefit from treatment with a HDL-raising or HDL mimicking agent, in particular a CETP inhibitor/modulator. A SNP biomarker for use in the invention can be predictive of either a therapeutic response (R) to treatment or non-response to treatment (NR). Table 2 shows genotypes observed in the dal-Outcomes cohort, present at the polymorphic site rs1967309, which can be used as a biomarker to predict response to dalcetrapib or HDL-raising or HDL mimicking agent, in particular to other CETP inhibitor/modulator. Table 4 shows genotypes observed in the dal-Outcomes and dal-Plaque-2 cohorts, present at the polymorphic site rs11647778, which can be used as a biomarker to predict response to dalcetrapib or HDL-raising or HDL mimicking agent, in particular to other CETP inhibitor/modulator. Each genotype shown in Table 2, to 5 alone or in combination with genotypes at other polymorphic sites can be used as a biomarker for predicting response to a HDL-raising or HDL mimicking agent, in particular to a CETP inhibitor/modulator).

Chem. 43:3566-3572 (2000) or WO 2007/051714, WO 2008/074677 or WO2011/000793.

Accordingly, the invention provides a method for the treatment or prevention of a cardiovascular disorder in a mammal, which method comprises administering to a mammal (preferably a mammal in need thereof) a therapeutically effective amount of the pharmaceutical composition. The mammal preferably is a human (i.e., a male or female human). The human can be of any race (e.g., Caucasian or Oriental).

The cardiovascular disorder particularly is atherosclerosis, peripheral vascular disease, dyslipidemia, hyperbetalipoproteinemia, hypoalphalipoproteinemia, hypercholesterolemia, hypertriglyceridemia, familial-hypercholesterolemia, angina, ischemia, cardiac ischemia, stroke, myocardial infarction, reperfusion injury, angioplastic restenosis, hypertension, and vascular complications of diabetes, obesity or endotoxemia.

A desirable dose is preferably about 300 mg to about 900 mg per day. A preferred dose is about 600 mg per day.

Genotyping Methods

Identification of the particular genotype of a DNA sample may be performed by any of a number of methods well known to one of skill in the art. For example, identification of the polymorphism can be accomplished by cloning of the allele and sequencing it using techniques well known in the art. Alternatively, the gene sequences can be amplified from genomic DNA, e.g. using PCR, and the product sequenced. Numerous methods are known in the art for isolating and analyzing a subject's DNA for a given genetic marker including polymerase chain reaction (PCR), ligation chain reaction (LCR) or ligation amplification and amplification methods such as self sustained sequence replication. Several non-limiting methods for analyzing a patient's DNA for mutations at a given genetic locus are described below.

DNA microarray technology, e.g., DNA chip devices and high-density microarrays for high-throughput screening applications and lower-density microarrays, may be used. Methods for microarray fabrication are known in the art and include various inkjet and microjet deposition or spotting technologies and processes, in situ or on-chip photolithographic oligonucleotide synthesis processes, and electronic DNA probe addressing processes. The DNA microarray hybridization applications has been successfully applied in the areas of gene expression analysis and genotyping for point mutations, single nucleotide polymorphisms (SNPs), and short tandem repeats (STRs). Additional methods include interference RNA microarrays and combinations of microarrays and other methods such as laser capture micro-dissection (LCM), comparative genomic hybridization (CGH) and chromatin immunoprecipitation (ChiP). See, e.g., He et al. (2007) Adv. Exp. Med. Biol. 593: 117-133 and Heller (2002) Annu. Rev. Biomed. Eng. 4: 129-153. Other methods include PCR, xMAP, invader assay, mass spectrometry, and pyrosequencing (Wang et al. (2007) Microarray Technology and Cancer Gene Profiling Vol 593 of book series Advances in Experimental Medicine and Biology, pub. Springer New York).

Another detection method is allele specific hybridization using probes overlapping the polymorphic site and having about 5, or alternatively 10, or alternatively 20, or alternatively 25, or alternatively 30 nucleotides around the polymorphic region. For example, several probes capable of hybridizing specifically to the allelic variant or genetic marker of interest are attached to a solid phase support, e.g., a “chip”. Oligonucleotide probes can be bound to a solid support by a variety of processes, including lithography. Mutation detection analysis using these chips comprising oligonucleotides, also termed “DNA probe arrays” is described e.g., in Cronin et al. (1996) Human Mutation 7′:244.

In other detection methods, it is necessary to first amplify at least a portion of the gene prior to identifying the allelic variant. Amplification can be performed, e.g., by PCR and/or LCR or other methods well known in the art.

In some cases, the presence of the specific allele in DNA from a subject can be shown by restriction enzyme analysis. For example, the specific nucleotide polymorphism can result in a nucleotide sequence comprising a restriction site which is absent from the nucleotide sequence of another allelic variant.

In a further embodiment, protection from cleavage agents (such as a nuclease, hydroxylamine or osmium tetroxide and with piperidine) can be used to detect mismatched bases in RNA/RNA DNA/DNA, or RNA/DNA heteroduplexes (see, e.g., Myers et al. (1985) Science 230: 1242). In general, the technique of “mismatch cleavage” starts by providing duplexes formed by hybridizing a probe, e.g., RNA or DNA, which is optionally labeled, comprising a nucleotide sequence of the allelic variant of the gene with a sample nucleic acid, obtained from a tissue sample. The double-stranded duplexes are treated with an agent that cleaves single-stranded regions of the duplex such as those formed from base pair mismatches between the control and sample strands. For instance, RNA/DNA duplexes can be treated with RNase and DNA/DNA hybrids treated with SI nuclease to enzymatically digest the mismatched regions. Alternatively, either DNA/DNA or RNA/DNA duplexes can be treated with hydroxylamine or osmium tetroxide and with piperidine in order to digest mismatched regions. After digestion of the mismatched regions, the resulting material is then separated by size on denaturing polyacrylamide gels to determine whether the control and sample nucleic acids have an identical nucleotide sequence or in which nucleotides they are different. See, for example, U.S. Pat. No. 6,455,249; Cotton et al. (1988) Proc. Natl. Acad. Sci. USA 85:4397; Saleeba et al. (1992) Meth. Enzymol. 217:286-295.

Alterations in electrophoretic mobility may also be used to identify the particular allelic variant. For example, single strand conformation polymorphism (SSCP) may be used to detect differences in electrophoretic mobility between mutant and wild type nucleic acids (Orita et al. (1989) Proc Natl. Acad. Sci USA 86:2766; Cotton (1993) Mutat. Res. 285: 125-144 and Hayashi (1992) Genet. Anal. Tech. Appl. 9:73-79). Single-stranded DNA fragments of sample and control nucleic acids are denatured and allowed to renature. The secondary structure of single-stranded nucleic acids varies according to sequence; the resulting alteration in electrophoretic mobility enables the detection of even a single base change. The DNA fragments may be labeled or detected with labeled probes. The sensitivity of the assay may be enhanced by using RNA (rather than DNA), in which the secondary structure is more sensitive to a change in sequence. In another preferred embodiment, the subject method utilizes heteroduplex analysis to separate double stranded heteroduplex molecules on the basis of changes in electrophoretic mobility (Keen et al. (1991) Trends Genet. 7:5).

The identity of the allelic variant or genetic marker may also be obtained by analyzing the movement of a nucleic acid comprising the polymorphic region in polyacrylamide gels containing a gradient of denaturant, which is assayed using denaturing gradient gel electrophoresis (DGGE) (Myers et al. (1985) Nature 313:495). When DGGE is used as the method of analysis, DNA will be modified to ensure that it does not completely denature, for example by adding a GC clamp of approximately 40 bp of high-melting GC-rich DNA by PCR. In a further embodiment, a temperature gradient is used in place of a denaturing agent gradient to identify differences in the mobility of control and sample DNA (Rosenbaum and Reissner (1987) Biophys. Chem. 265: 1275).

Examples of techniques for detecting differences of at least one nucleotide between 2 nucleic acids include, but are not limited to, selective oligonucleotide hybridization, selective amplification, or selective primer extension. For example, oligonucleotide probes may be prepared in which the known polymorphic nucleotide is placed centrally (allele-specific probes) and then hybridized to target DNA under conditions which permit hybridization only if a perfect match is found (Saiki et al. (1986) Nature 324: 163); Saiki et al. (1989) Proc. Natl. Acad. Sci. USA 86:6230). Such allele specific oligonucleotide hybridization techniques are used for the detection of the nucleotide changes in the polymorphic region of the gene. For example, oligonucleotide probes having the nucleotide sequence of the specific allelic variant are attached to a hybridizing membrane and this membrane is then hybridized with labeled sample nucleic acid. Analysis of the hybridization signal will then reveal the identity of the nucleotides of the sample nucleic acid.

Alternatively, allele specific amplification technology which depends on selective PCR amplification may be used in conjunction with the instant invention. Oligonucleotides used as primers for specific amplification may carry the allelic variant of interest in the center of the molecule (so that amplification depends on differential hybridization) (Gibbs et al. (1989) Nucl. Acids Res. 17:2437-2448) or at the extreme 3′ end of one primer where, under appropriate conditions, mismatch can prevent, or reduce polymerase extension (Prossner (1993) Tibtechl 1:238 and Newton et al. (1989) Nucl. Acids Res. 17:2503). This technique is also termed “PROBE” for PRobeOligo Base Extension. In addition it may be desirable to introduce a novel restriction site in the region of the mutation to create cleavage-based detection (Gasparini et al. (1992) Mol. Cell. Probes 6: 1).

In another embodiment, identification of the allelic variant or genetic marker is carried out using an oligonucleotide ligation assay (OLA), as described, e.g., in U.S. Pat. No. 4,998,617 and in Laridegren, U. et al. Science 241: 1077-1080 (1988). The OLA protocol uses two oligonucleotide probes which are designed to be capable of hybridizing to abutting sequences of a single strand of a target. One of the oligonucleotides is linked to a separation marker, e.g., biotinylated, and the other is detectably labeled. If the precise complementary sequence is found in a target molecule, the oligonucleotides will hybridize such that their termini abut, and create a ligation substrate. Ligation then permits the labeled oligonucleotide to be recovered using avidin, or another biotin ligand. Nickerson, D. A. et al. have described a nucleic acid detection assay that combines attributes of PCR and OLA (Nickerson, D. A. et al. (1990) Proc. Natl. Acad. Sci. USA 87:8923-8927). In this method, PCR is used to achieve the exponential amplification of target DNA, which is then detected using OLA. A variation of the OLA method as described in Tobe et al. (1996) Nucleic Acids Res. 24: 3728 each allele specific primers is labeled with a unique hapten, i.e. digoxigein and flourescein and each OLA reaction is detected using hapten specific antibodies labeled with reporter enzymes.

The invention provides methods for detecting a single nucleotide polymorphism (SNP) in ADCY9. Because single nucleotide polymorphisms are flanked by regions of invariant sequence, their analysis requires no more than the determination of the identity of the single variant nucleotide and it is unnecessary to determine a complete gene sequence for each patient. Several methods have been developed to facilitate the analysis of SNPs.

The single base polymorphism can be detected by using a specialized exonuclease-resistant nucleotide, as disclosed, e.g., in U.S. Pat. No. 4,656,127. According to the method, a primer complementary to the allelic sequence immediately 3′ to the polymorphic site is permitted to hybridize to a target molecule obtained from a particular animal or human. If the polymorphic site on the target molecule contains a nucleotide that is complementary to the particular exonuclease-resistant nucleotide derivative present, then that derivative will be incorporated onto the end of the hybridized primer. Such incorporation renders the primer resistant to exonuclease, and thereby permits its detection. Since the identity of the exonuclease-resistant derivative of the sample is known, a finding that the primer has become resistant to exonucleases reveals that the nucleotide present in the polymorphic site of the target molecule was complementary to that of the nucleotide derivative used in the reaction. This method has the advantage that it does not require the determination of large amounts of extraneous sequence data.

A solution-based method may also be used to determine the identity of the nucleotide of the polymorphic site (WO 91/02087). As above, a primer is employed that is complementary to allelic sequences immediately 3′ to a polymorphic site. The method determines the identity of the nucleotide of that site using labeled dideoxynucleotide derivatives, which, if complementary to the nucleotide of the polymorphic site will become incorporated onto the terminus of the primer.

An alternative method is described in WO 92/15712. This method uses mixtures of labeled terminators and a primer that is complementary to the sequence 3′ to a polymorphic site. The labeled terminator that is incorporated is thus determined by, and complementary to, the nucleotide present in the polymorphic site of the target molecule being evaluated. The method is usually a heterogeneous phase assay, in which the primer or the target molecule is immobilized to a solid phase.

Many other primer-guided nucleotide incorporation procedures for assaying polymorphic sites in DNA have been described (Komher, J. S. et al. (1989) Nucl. Acids. Res. 17:7779-7784; Sokolov, B. P. (1990) Nucl. AcidsRes. 18:3671; Syvanen, A.-C, et al. (1990) Genomics 8:684-692; Kuppuswamy, M. N. et al. (1991) Proc. Natl. Acad. Sci. USA 88: 1143-1147; Prezant, T. R. et al. (1992) Hum. Mutat. 1:159-164; Ugozzoli, L. et al. (1992) GATA 9: 107-112; Nyren, P. et al. (1993) Anal. Biochem. 208: 171-175). These methods all rely on the incorporation of labeled deoxynucleotides to discriminate between bases at a polymorphic site.

Moreover, it will be understood that any of the above methods for detecting alterations in a gene or gene product or polymorphic variants can be used to monitor the course of treatment or therapy.

The methods described herein may be performed, for example, by utilizing pre-packaged diagnostic kits, such as those described below, comprising at least one probe, primer nucleic acid, or reagent which may be conveniently used for genotyping, e.g., analyzing a genetic marker present in the ADCY9 gene to determine whether an individual has an increased likelihood of benefiting from treatment with HDL-raising or mimicking agent including a HDL-raising or HDL mimicking agent, in particular a CETP inhibitor/modulator. In particular the genetic markers are as described herein.

In other aspects a primer comprises 100 or fewer nucleotides, in certain aspects from 12 to 50 nucleotides or from 12 to 30 nucleotides. The primer is at least 70% identical to the contiguous sequence or to the complement of the contiguous nucleotide sequence, preferably at least 80% identical, and more preferably at least 90% identical. A primer or probe of the invention is preferably 15-50 nucleotides in length comprising a region of 15 to 20 nucleotides that is complimentary to a sequence selected from SEQ. ID. NO 1-21, in particular is complementary to sequence SEQ. ID No 1, 19 or 21. The degree of complimentary between a probe or primer and SEQ. ID. NO. 1-21 maybe 100%, 95%, 90%, 85%, 80% or 75%.

Oligonucleotides, including probes and primers, “specific for” a genetic allele or genetic marker bind either to the polymorphic region of a gene or bind adjacent to the polymorphic region of the gene. For oligonucleotides that are to be used as primers for amplification, primers are adjacent if they are sufficiently close to be used to produce a polynucleotide comprising the polymorphic region. In one embodiment, oligonucleotides are adjacent if they bind within about 1-2 kb, e.g. less than 1 kb from the polymorphism. Specific oligonucleotides are capable of hybridizing to a sequence, and under suitable conditions will not bind to a sequence differing by a single nucleotide.

Oligonucleotides of the invention, whether used as probes or primers, can be detectably labeled. Labels can be detected either directly, for example for fluorescent labels, or indirectly. Indirect detection can include any detection method known to one of skill in the art, including biotin-avidin interactions, antibody binding and the like. Fluorescently labeled oligonucleotides also can contain a quenching molecule. Oligonucleotides can be bound to a surface. In some embodiments, the surface is silica or glass. In some embodiments, the surface is a metal electrode.

Probes can be used to directly determine the genotype of the sample or can be used simultaneously with or subsequent to amplification. The term “probes” includes naturally occurring or recombinant single- or double-stranded nucleic acids or chemically synthesized nucleic acids. They may be labeled by nick translation, Klenow fill-in reaction, PCR or other methods known in the art. Probes of the present invention, their preparation and/or labeling are described in Sambrook et al. (1989) supra. A probe can be a polynucleotide of any length suitable for selective hybridization to a nucleic acid containing a polymorphic region of the invention. Length of the probe used will depend, in part, on the nature of the assay used and the hybridization conditions employed.

Labeled probes also can be used in conjunction with amplification of a polymorphism. (Holland et al. (1991) Proc. Natl. Acad. Sci. USA 88:7276-7280). U.S. Pat. No. 5,210,015 describes fluorescence-based approaches to provide real time measurements of amplification products during PCR. Such approaches have either employed intercalating dyes (such as ethidium bromide) to indicate the amount of double-stranded DNA present, or they have employed probes containing fluorescence-quencher pairs (also referred to as the “TaqMan®” approach) where the probe is cleaved during amplification to release a fluorescent molecule whose concentration is proportional to the amount of double-stranded DNA present. During amplification, the probe is digested by the nuclease activity of a polymerase when hybridized to the target sequence to cause the fluorescent molecule to be separated from the quencher molecule, thereby causing fluorescence from the reporter molecule to appear. The TaqMan® approach uses a probe containing a reporter molecule—quencher molecule pair that specifically anneals to a region of a target polynucleotide containing the polymorphism.

Probes can be affixed to surfaces for use as “gene chips.” Such gene chips can be used to detect genetic variations by a number of techniques known to one of skill in the art. In one technique, oligonucleotides are arrayed on a gene chip for determining the DNA sequence of a by the sequencing by hybridization approach, such as that outlined in U.S. Pat. Nos. 6,025,136 and 6,018,041. The probes of the invention also can be used for fluorescent detection of a genetic sequence. Such techniques have been described, for example, in U.S. Pat. Nos. The probes of the invention also can be used for fluorescent detection of a genetic sequence. Such techniques have been described, for example, in U.S. Pat. Nos. 5,968,740 and 5,858,659. A probe also can be affixed to an electrode surface for the electrochemical detection of nucleic acid sequences such as described in U.S. Pat. No. 5,952,172 and by Kelley, S. O. et al. (1999) Nucl. Acids Res. 27:4830-4837. One or more probes for detecting the SNP of the invention (Table 2, 3, 4, 5 or 10, in particular Table 4) can be affixed to a chip and such a device used to predict response to HDL-raising or HDL mimicking agent, in particular CETP inhibitor/modulator and select an effective treatment for an individual with cardiovascular disease. It is conceivable that probes for detecting the SNP of the invention could be included on a chip with a variety of other probes for uses other than predicting response to a HDL-raising or HDL mimicking agent, in particular CETP inhibitor/modulator.

Additionally, synthetic oligonucleotides used as probes or primers may be modified to become more stable. Exemplary nucleic acid molecules which are modified include uncharged linkages such as phosphoramidate, phosphothioate and methylphosphonate analogs of DNA (see also U.S. Pat. Nos. 5,176,996; 5,264,564 and 5,256,775). Primers and probes of the invention can include for example, labeling methylation, inter-nucleotide modification such as pendent moieties (e.g., polypeptides), intercalators (e.g., acridine, psoralen), chelators, alkylators, and modified linkages (e.g., alpha anomeric nucleic acids). Also included are synthetic molecules that mimic nucleotide acid molecules in the ability to bind to a designated sequence by hydrogen bonding and other chemical interactions, including peptide linkages that substitute for phosphate linkages in the nucleotide backbone.

The invention relates to synthetic oligonucleotide molecules, primers and probes that hybridize under high stringency hybridization conditions to naturally occurring oligonucleotides described herein, gene markers of the ADCY9 gene. Oligonucleotides can be detected and/or isolated by specific hybridization, under high stringency conditions. “High stringency conditions” are known in the art and permit specific hybridization of a first oligonucleotide to a second oligonucleotide where there is a high degree of complementarity between the first and second oligonucleotide. For the genotyping methods disclosed herein this degree of complementarity is between 80% and 100% and preferably between 90% and 100% The SNPs of the invention can also be detected from pre-existing data, such as whole genome sequence data present in a data base. The invention provides a computer implemented method of querying genomic data to determine a genotype for predicting the response of a patient to a CETP inhibitor and treating said patient accordingly i.e. treating responder patients with a CETP inhibitor.

Sample nucleic acid for use in the genotyping methods, treatment selection or methods of treatment can be obtained from any cell type or tissue of a subject. For example, a subject's bodily fluid, a sample, (e.g. blood) can be obtained by known techniques. Alternatively, nucleic acid tests can be performed on dry samples (e.g., hair or skin). More particularly, the sample nucleic acid for genotyping methods, treatment selection or methods of treatment will be obtained from blood cell type.

The invention described herein relates to methods and reagents useful for determining and identifying the allele present on the ADCY9 gene at rs11647778 and optionally rs1967309, rs2238448 or rs12595857, or any other genetic variant in linkage disequilibrium with these SNPs such as displayed in FIGS. 8 and 9, spanning from position chr16:4049365 to chr16:4077178 (assembly GRCh37/hg 19). In particular the invention also relates to methods and reagents for determining and identifying the allele present in the ADCY9 gene at rs11647778 and optionally rs1967309, rs12595857, rs2239310, rs11647828, rs8049452, rs12935810, rs74702385, rs17136707, rs8061182, rs111590482, rs4786454, rs2283497, rs2531967, rs3730119, rs13337675, rs2238448 more particularly at rs11647778 and optionally rs1967309 and/or rs12595857, and most particularly at rs11647778 and optionally rs1967309.

As set forth herein, the invention also provides treatment selection methods comprising detecting one or more genetic markers present in the ADCY9 gene. In some embodiments, the methods use probes or primers comprising nucleotide sequences which are complementary to a polymorphic region of ADCY9. Accordingly, the invention provides kits comprising probes and primers for performing the genotyping methods of the invention.

In some embodiments, the invention provides kits useful for determining whether a patient with a cardiovascular disorder has an increased likelihood of benefiting from treatment with a HDL-raising or HDL mimicking agent, in particular a CETP inhibitor/modulator. Such kits contain one of more of the reagents, in particular primers or probes, described herein and instructions for use. As an example only, the invention also provides kits useful for determining whether a patient with cardiovascular disorder has an increased likelihood of benefiting from treatment with thioisobutyric acid S-(2-{[1-(2-ethyl-butyl)-cyclohexanecarbonyl]-amino}-phenyl) ester comprising a first oligonucleotide and a second oligonucleotides specific for a CC polymorphism in the ADCY9 rs11647778 SNP and optionally for a AA polymorphism in the ADCY9 rs1967309 SNP.

The kits can comprise at least one probe or primer that is capable of specifically hybridizing to the polymorphic region of ADCY9 and instructions for use. The kits can comprise at least one of the above described nucleic acids. Kits useful for amplifying at least a portion of ADCY9 generally comprise two primers, at least one of which is capable of hybridizing to the allelic variant sequence. Such kits are suitable for detection of genotype by, for example, fluorescence detection, by electrochemical detection, or by other detection.

Yet other kits of the invention comprise at least one reagent useful to perform the assay. For example, the kit can comprise an enzyme. Alternatively the kit can comprise a buffer or any other useful reagent.

The kits can include all or some of the positive controls, negative controls, reagents, primers, sequencing markers, probes and antibodies described herein for determining the subject's genotype in the polymorphic region of ADCY9.

Example 1

Dal-OUTCOMES trial (NC20971) was a double blind, randomized, placebo-controlled, parallel group, multi-center, phase III study to assess the safety and efficacy of the CETP inhibitor dalcetrapib in patients recently hospitalized for an Acute Coronary Syndrome (ACS). At time of the interim analysis the study included 15871 randomized patients, distributed over two treatment arms: placebo (7933 patients) and dalcetrapib (600 mg daily; 7938 patients). The study has shown no evidence of reduction of the event rate in the primary efficacy endpoint in the dalcetrapib arm compared to the placebo arm. The dal-OUTCOMES study details can be found in G. Schwartz et al., N. Engl. J. Med. 367; 22, 2012.

dal-Outcomes patients were recruited 4 to 12 weeks following hospitalization for acute coronary syndrome characterized by elevated cardiac biomarkers, with symptoms of acute myocardial ischemia, ischemic electrocardiographic abnormalities that were new or presumed to be new, or loss of viable myocardium on imaging. Patients without elevated cardiac biomarkers were eligible to participate if symptoms of acute myocardial ischemia were accompanied by electrocardiographic changes that were new or presumed to be new and by additional evidence of obstructive coronary disease. (Schwartz G G et al. Am Heart J 2009; 158:896-901 e3). Patients who had a myocardial infarction associated with percutaneous coronary intervention were also eligible. All patients were following individualized programs to target LDL cholesterol levels of 100 mg per deciliter (2.6 mmol per liter) or lower by statin if tolerated and diet. No specific statin agent was specified, and patients were not excluded based on LDL cholesterol values. Patients with serum triglyceride levels of 400 mg per deciliter (4.5 mmol per liter) or higher were excluded. (Schwartz G G et al. N Engl J Med 2012; 367:2089-99) Eligible participants to the dal-Outcomes trial entered a single-blind placebo run-in period of approximately 4 to 6 weeks to allow for patients to stabilise and for completion of planned revascularisation procedures. At the end of the run-in period, eligible patients in stable condition were randomised in a 1:1 ratio to 600 mg of dalcetrapib or placebo on top of evidence-based medical care for acute coronary syndrome. Cardiovascular events were adjudicated by an independent clinical endpoint committee. For the pharmacogenomics study, 6338 patients were recruited from April 2008 through July 2010 at 461 sites in 14 countries and provided written informed consent to participate to the genetic study of the dal-OUTCOMES trial. DNA was extracted from whole blood. Following genomic data cleanup, samples from 5749 Caucasian patients were used for the discovery genome-wide association study (GWAS).

Genotyping

The Illumina Infinium HumanOmni2.5Exome-8v1_A BeadChip including 2,567,845 genetic variants (Illumina, San Diego, Calif.) was used for the discovery GWAS of 5749 Caucasian participants to the dal-OUTCOMES study. The chromosome 16 region including 5 genes upstream and downstream of the adenylate cyclase type 9 (ADCY9) gene (CHR16: 3,400,000-4,600,000) was imputed using IMPUTE2, providing 17,764 variants for analysis with an average completion rate of 99.76%. A Sequenom panel was used for the confirmation of imputed single nucleotide polymorphisms (SNPs) in the ADCY9 gene identified in dal-OUTCOMES and were tested in the dal-PLAQUE-2 study, including 20 SNPs with P values <0.05 from the discovery GWAS.

DNA was extracted from 1 ml of whole blood using the QiaSymphony DNA midi kit version 1.1 (Qiagen, Garstilgweg, Switzerland) and quantified using the QuantiFluor™ dsDNA System (Promega, Madison, Wis.) with an average concentration of 91.5 ng/μL and average yield of 18.3 μg. 97.9% of DNA samples had concentrations above 25 ng/μL. Agarose gel electrophoresis confirmed high quality of DNA with no signs of degradation. DNA was normalized to 50 ng/μL.

Genome-Wide Association Study (GWAS)—

Genome-wide genotyping was performed using 200 ng of genomic DNA in GLP-environment at the Beaulieu-Saucier Pharmacogenomics Centre (Montreal, Canada). The Illumina Infinium HumanOmni2.5Exome-8v1_A BeadChip (Illumina, San Diego, Calif.) including 2,567,845 genomic markers was used and processed according to the manufacturer's specifications. This chip includes over 200,000 exome variants identified through the Exome Chip Consortium. The remaining BeadChip content is a mix of rare and common SNPs from the 1000 Genome Project designed to be maximally informative for diverse world populations. Each BeadChip was scanned and analyzed using the Illumina iScan Reader. Scanned images were analyzed using Illumina's GenomeStudio version 2011.1 with the GenTrain 2.0 cluster algorithm, using a No-Call threshold of 0.15, without manual cluster adjustment and using the manufacturer's Illumina HumanOmni25Exome-8v1_A cluster file. Genotype data files were produced in three installments of comparable size as data became available.

Sequenom—

A single Sequenom panel was designed and validated using HapMap DNA samples. The panel included 27 SNPs in the ADCY9 gene selected according to: a P value 50.05 in the discovery GWAS (n=15), a P value <10⁻by imputation (n=6; 1 failed in development), predicted regulatory function (n=5; 1 excluded due to low MAF), or literature (n=4; 1 failed in production). The Sequenom MassArray Maldi-TOF System (Sequenom, La Jolla, Calif.) was used with Sequenom's Typer 4.0.22 Software. Each plate was clustered using autocluster and manually modified as needed. Two Coriell Institute DNA samples (NA11993 and NA07357) used as controls on each genotyping plate showed 100% concordance on all plate replicates and 100% concordance of genotype calls with expectations for corresponding SNPs in the 1000 Genomes and HapMap reference database. 17 SNPs genotyped on both the GWAS and Sequenom panel provided a mean genotypic concordance of 99.95% (min: 99.41, max: 100.00%), and 11 SNPs previously imputed provided a mean genotypic concordance with the most likely genotype (>0.80 imputation probability) of 99.75 (min: 98.48, max: 99.96).

Genomic Quality Checks

Dal-Outcomes Discovery GWAS.

Three genotyping files in PLINK format generated by GenomeStudio were combined and transformed to binary PLINK format. GenomeStudio Final report files were used to generate gender plots, LRR and BAF graphics. PyGenClean (Lemieux Perreault L P et al. Bioinformatics 2013; 29:1704-5) and PLINK version 1.07 were used for the quality checks (QC) and genetic data cleanup process. The genotyping experiment consisted of 68 plates of DNA samples. On each plate, there were two controls, one Coriell DNA alternating from four pre-selected samples (NA 11993, NA11992, NA10860 and NA12763) and one internal DNA control from four pre-selected samples. The pairwise concordance of Coriell samples ranged from 0.999807 to 0.999958. Pairwise concordance of the four internal controls ranged from 0.99976 to 0.99995. The comparison of Coriell genotypes to expectation from the 1000 Genomes data provided concordance ranging from 0.996028 to 0.997783.

Detailed genetic data cleanup steps are presented in Table 9. Duplicated SNPs were evaluated for concordance, completion rate, allele call and MAF. SNPs with different allele calls or different MAF were retained. Identical and concordant SNPs were merged. Genotyping completion rate for samples and SNPs was set to 98%. SNPs with genotyping plate bias (based on the 96 well plates used to dilute DNA samples) were flagged but not removed as the effect of genetic ancestry could not be excluded. Pairwise identity-by-state (IBD) was used to conduct close familial relationship checks. All but one pair-member of related pairs and sample duplicates (IBS2*ratio >0.80) were flagged and removed based on a selection of uncorrelated SNPs (r²<0.1). The pairwise IBS matrix was used as a distance metric to identify cryptic relatedness among samples and sample outliers by multi-dimensional scaling (MDS). The first two MDS components of each subject were plotted including the genotypes of HapMap CEU, JPT-CHB, and YRI data (keeping only founder individuals). Outliers from the main Caucasian cluster were flagged and removed by k-nearest neighbour (FIG. 5). The scree plot and the cumulative explained variance were computed using the smartpca program of the EIGENSOFT suite (version 3.0). Options used were a numoutlieriter (maximum number of outlier removal iterations) of 0 (turned off) and altnormstyle (normalization formula) equal to NO. (Price A L Nat Genet 2006; 38:904-9) (FIG. 6)

Imputation

The chromosome 16 region including 5 genes upstream and downstream of ADCY9 (CHR16: 3,401,847-4,598,558; NCBI build GRCh37) was imputed using the programs IMPUTE2 (version 2.3.0) and GTOOL (version 0.7.0) on Linux with 1096 genotyped SNPs and 5749 dal-Outcomes Caucasian samples. (Howie B N et Al. PLoS Genet 2009; 5:e1000529) Strand alignment was solved by automatically flipping non A/T and C/G SNPs according to position. Ambiguous A/T and C/G SNPs were considered missing and were imputed. The Impute2 reference package ALL_1000G_phase1 integrated_v3_chr16_impute was used for imputation. We used a cut-off of 0.80 for imputed genotype probabilities per genotype and per individual and a completion rate of 98% or higher. There remained 17,764 variants for analysis with an average completion rate of 99.76%.

Of 1,223,798 common SNPs analyzed, a single region with genome-wide significance was found to be associated with cardiovascular events by Cox proportional hazards modeling in the dalcetrapib arm, identifying a SNPs in the ADCY9 gene on chromosome 16: rs1967309 (P=2.41×10⁻⁸) (FIG. 1A). The genetic variant at this position has a minor allele frequency of 0.41, and the additive genetic effect of one allele (A) has a HR=0.65 (95% CI 0.56, 0.76) for cardiovascular events in the dalcetrapib arm (Table 12a). Neighbouring SNPs in linkage disequilibrium with rs1967309 and which provided lower, but supporting evidence for association were located in a common recombination block (FIG. 1B). Imputation in this region identified 9 additional SNPs in the ADCY9 gene with P<10^(−s), including 6 with P<10⁶ (FIG. 10). None of the 835,255 rare SNPs analyzed in 36,268 SKAT gene sets passed the significance threshold for follow-up.

There was no detectable genetic effect for rs1967309 in the placebo arm alone (Cox proportional-hazards, HR=0.92; P=0.25) (Table 12b). The gene-by-treatment arm interaction term was indicative of a statistical interaction (P=0.0014; beta: −0.340). Stratification by genotypes in the dalcetrapib arm shows that homozygotes for the minor allele (AA) and heterozygotes (AG) at rs1967309 have respectively HR=0.40 (95% CI 0.28, 0.57) and HR=0.68 (95% CI 0.55, 0.84) for cardiovascular events when compared to reference GG homozygotes (FIG. 3). Considering only patients with the homozygous genotype AA at rs1967309 (n=961), there was a 39% reduction in the pre-specified composite endpoint of coronary heart disease death, resuscitated cardiac arrest, non-fatal myocardial infarction, non-fatal ischemic stroke, unstable angina or unanticipated coronary revascularization with dalcetrapib compared to placebo (HR=0.61; 95% CI 0.41, 0.92). Similar results were observed when coronary revascularizations were removed from the primary endpoint (HR=0.60; 95% CI 0.35, 1.02). When considering only patients with the homozygous genotype GG at rs1967309 (n=1984), there was a 27% increase in cardiovascular events for treatment with dalcetrapib versus placebo (HR=1.27; 95% CI 1.02, 1.58). Heterozygous carriers had an intermediate response (n=2796; HR=0.94; 95% CI 0.77, 1.16). Results were confirmed by genotyping 27 SNPs in the ADCY9 gene by Sequenom technology (Table 10).

A total of eight polymorphisms (genotyped or imputed) were associated with P values less than 10⁻⁶ in the discovery cohort of 5749 patients from the pharmacogenomic study of the dal OUTCOMES trial, with the prespecified primary composite endpoint of coronary heart disease death, resuscitated cardiac arrest, non-fatal myocardial infarction, non-fatal ischemic stroke, unstable angina with objective evidence of ischemia or coronary revascularization. In this discovery genome-wide analysis, two of these eight SNPs in the ADCY9 gene were associated with P-values less than 5×10⁻⁸. For the polymorphic nucleotide rs1967309, patients with the AA genotype (minor, or less common, allele) benefited from a reduction in cardiovascular events of 39% when treated with dalcetrapib compared to placebo, whereas those with the GG genotype (major allele) were exposed to a 27% increase in risk. Heterozygous patients with the AG genotype had an intermediate response. These results were only observed with dalcetrapib, not in the placebo arm, and there were statistical interactions between the polymorphisms and the study arm (dalcetrapib versus placebo) in the association with clinical events thus strengthening the link with the ADCY9 gene. Hazard ratios were similar when coronary revascularizations were removed from the analysis, which provided a direct comparison with the primary composite endpoint of the global dal-OUTCOMES trial (coronary heart disease, resuscitated cardiac arrest, non-fatal myocardial infarction, non-fatal ischemic stroke or unstable angina). All eight polymorphisms were in strong linkage disequilibrium (r²>0.77), which reinforces the postulate that this region of the ADCY9 gene determines clinical responses to dalcetrapib.

Plasma Lipids

Genotypes of rs1967309 SNPs were significantly associated with changes over time in lipids induced by dalcetrapib in dal-OUTCOMES. Using univariate statistics, genotypes were associated with change in total cholesterol at 1 month (P=0.0001; P=0.004 when controlling for gender and genetic ancestry): GG genotype carriers had a smaller increase (10.0±23.3 mg/dl) compared to AG (12.9±30.3) and AA (13.8±24.0) carriers. This effect was not observed in the placebo arm. A similar result was observed for change in LDL-cholesterol after 1 month of dalcetrapib treatment: Changes were −2.0±20.0, −1.0±20.0 and +0.6±21.0 mg/dl in GG, AG and AA genotype carriers of rs1967309 respectively (P=0.003 univariate; adjusted P=0.006). During the dalcetrapib treatment period, GG carriers had overall slightly lower LDL-cholesterol levels (adjusted P=0.048; repeated measures analysis, FIG. 4).

Example 2

The dal-PLAQUE-2 study (Tardif J C et al, Circulation Cardiovascular imaging 2011; 4:319-33) was a phase 3b multicenter, double-blind, randomized, placebo-controlled, parallel group trial designed to evaluate the effect of dalcetrapib on atherosclerotic disease progression in patients with evidence of coronary artery disease and carotid intima media thickness of at least 0.65 mm in the far wall of the common carotid arteries, as assessed by B-mode ultrasonography. A total of 931 patients were randomized to receive dalcetrapib 600 mg daily or matching placebo with intended treatment duration of 24 months. However, the trial was terminated prematurely concurrent with the termination of dal OUTCOMES (the latter due to futility). Patients continued to study medication until they returned for follow-up carotid imaging at 12 months. Carotid B-mode ultrasound recordings at baseline, month 6, and month 12 were analyzed centrally at the core laboratory of the Montreal Heart Institute. Intima-media thickness (IMT) was analyzed on the far wall of the common carotid arteries. A segment of 10 mm in length of the common carotid artery was analyzed on serial examinations using an automated edge detection software (Carotid Analyzer, Medical Imaging Applications, Coralville, Iowa). Among the 411 participants in the dal-PLAQUE-2 trial who consented to the genetic study, 386 had imaging measures at baseline, 6 months and 12 months (194 and 192 in the dalcetrapib and placebo arms respectively). DNA was extracted from whole blood. The research protocols were approved by the relevant institutional review boards or ethics committees and all human participants gave written informed consent.

Central Analysis of Carotid Imaging Examinations in the Dal-Plaque-2 Trial

All acquired carotid ultrasound recordings were analyzed at the core laboratory of the Montreal Heart Institute by experienced technicians supervised by a physician. Images were required to meet quality and inclusion and exclusion criteria for eligibility prior to random assignment to study treatment. The methods for carotid intima-media thickness analysis included side-by-side viewing of baseline and follow-up studies.

Carotid arterial wall segments were assessed in a longitudinal view, perpendicular to the ultrasound beam, with a horizontal display of the arterial image in order to view the interfaces between blood and vascular structures on the longest possible segment. The localization of the end of the common carotid artery was used as the landmark in repositioning and analyzing comparative length of segments in baseline and follow-up studies. Intima-media thickness was analyzed on the far wall of the right and left common carotid arteries, to reduce variability of measurements. The average of the mean intima-media thickness values of the right and left common carotid arteries was used. A matched segment of 10 mm in length of the common carotid artery was analyzed on serial examinations (baseline, 6 months and 12 months), starting 5 mm proximal to the carotid bifurcation. The edge detection software Carotid Analyzer (Medical Imaging Applications LLC, Coralville, Iowa) was used to analyze intima-media thickness using the automated option. Two sets of carotid artery borders were identified: First, the media-adventitia borders were determined and verified by the reader. When required, their locations were semi-automatically modified to the correct location. When these borders were approved, the lumen-intima boundaries were automatically detected using the media-adventitia borders for guidance. Frames from looped sequences of intima-media thickness were selected for reading, and poor quality outlier frames were removed from the analysis when required.

Of the 27 SNPs selected for genotyping by Sequenom, 20 SNPs in the ADCY9 gene had P<0.05 in the discovery cohort. We tested for association with those SNPs in the dal-PLAQUE-2 trial in order to obtain supporting evidence for association by relying on imaging data obtained after 6 and 12 months of treatment in the dalcetrapib arm (n=194). Ten out of 20 SNPs provided association with IMT measures in dal-PLAQUE-2 (P<0.05, Table 13). Notably, marker rs2238448 (which was in linkage disequilibrium with rs1967309 (r²=0.80)) was associated with IMT in dal-plaque-2 (P=0.009) and with events in dal-OUTCOMES (P=8.88×10⁸; HR=0.67, 95% CI 0.58, 0.78). After 12 months of treatment with dalcetrapib, changes in IMT were −0.027±0.079 mm in homozygote carriers of the minor allele (TT), 0.000±0.048 mm for heterozygotes, and +0.009±0.038 mm for homozygous carriers of the common allele (CC) at rs2238448 (P=0.009). This effect emerged at 6 months. All 20 SNPs displayed a decrease in IMT in agreement with the genotype group that showed reduced cardiovascular risk in the dal-OUTCOMES trial (Table 13). None of the genotyped SNPs showed association in the placebo arm (all P>0.05). Only the gene-by-treatment interaction term of rs2531967 reached significance (P=0.024) in dal-PLAQUE-2, probably due to the small sample size. SNP rs1967309 did not reach significance in dal-PLAQUE-2 (P=0.114), but the reduction in IMT was of similar magnitude to that with rs2238448 and consistent with the findings in dal-OUTCOMES. After 12 months of treatment with dalcetrapib, changes in IMT were −0.021±0.083 mm in AA homozygotes, −0.001±0.048 mm for heterozygotes, and +0.005±0.042 mm for GG homozygotes at rs1967309.

Statistical Analyses for Both Examples 1 and 2

Genome-wide association tests were performed using JMP Genomics software version 6.1. significant results were validated in SAS software (v. 9.3) (SAS Institute Inc., Cary, N.C., USA). The 1-degree of freedom additive genetic test was used where genotypes were coded as 0, 1 or 2, according to the count of minor alleles. In the presence of covariates, the P value for the additive genetic test is adjusted for the covariate such

log ⁡ ( r 1 - r ) = b 0 + b 1 ⁢ ⁢ add + ∑ j ⁢ ⁢ b ⁢ cov ⁢ ⁢ or log ⁡ ( event ⁢ ⁢ rate ) = b 0 + b 1 ⁢ ⁢ add + ∑ j ⁢ ⁢ b ⁢ cov ; where r is the probability of having the event and where the null (H₀) under the additive genetic test is of b₁=0. A Cox proportional hazards regression model was used to test for gene-by-treatment interaction according to: log (event rate)˜genotype+treatment arm+genotype*treatment arm+sex+principal components, using both treatment and placebo arm samples. The GWAS discovery models included adjustment for sex and the 5 principal components for genetic ancestry. MAF were calculated using samples from both treatment arms. Rare variants (MAF<0.05) were analyzed jointly within genes using the sequence kernel association test (SKAT) (Wu M C et al, Am J Hum Genet 2011; 89:82-93). including covariates and using a beta-weighting function with parameters a₁ set to 1 and a₂ set to 25. Variants positioned between two genes were analyzed as a distinct set.

For the dal-Plaque-2 population, mixed regression models for repeated measures analysis were tested in SAS software. The dal-Plaque-2 tested endpoint was the mean of IMT measures of common carotid arteries at the 6-month and the 12-month visits, using the baseline measure as covariate. Adjustment of the significance threshold for multiple testing of the 27 SNPs genotyped on the Sequenom panel was not performed, due to the highly correlated nature of the selected SNPs. As reference, the number of independent tests (Mefr) was estimated using the method of Gao et al, Genet Epidemiol 2008; 32:361-9. to Merr=8, using the dal-Outcomes population sample.

For the linkage disequilibrium plots (FIGS. 8 and 9), Haploview (version 4.2)(Barrett J C et al. Bioinformatics 2005; 21:263-5) was used to display linkage disequilibrium r² values in a pair-wise matrix plot with a colour heat plot of D′ values. Blocks of linkage disequilibrium were constructed using the confidence interval method set to [0.70, 0.98], upper confidence maximum for strong recombination 0.9 and the fraction of strong LD in informative comparisons ≥0.95.
